Train by effort.
Race by data.

Pace It reads up to 10 years of runs from Apple Health when you install. Trends populate on day 1.

Integrations might take a few minutes to sync, but your data will still be available on day 1.

Pace-at-effort trends show how your running pace improves at the same heart rate over time. Instead of just tracking speed, Pace It analyzes how efficiently you run at different effort levels (heart rate zones).

This helps you answer many critical questions in training such as "am I getting faster at the same effort?", "What is my current 10k or threshold pace?" and "If my fitness has changed, what pace should I train at today?"

By comparing pace at similar effort levels and automatically recalibrating your training paces you can clearly see long-term progress, fatigue, or plateaus and adjust your training accordingly.

No, you can start using Pace It immediately without creating an account. There are no logins and no unnecessary onboarding steps. Simply download the app, connect your device, and start running.

Pace It is designed with a privacy-first architecture. Your running data is processed directly on your device, not on external servers.

Runs sync from Apple Health on your device. When you connect integrations, activity data is securely synced through our server only to deliver it to your device. No personal identity information (PII) is stored, and no performance analysis is performed.

All analytics, including pace insights and performance trends, are computed locally on your device. This ensures faster insights, stronger privacy, and full control over your data.

Yes, Pace It is compatible with Strava. You can:

• Import your runs in up to 200-day cycles
• Automatically sync new runs to Strava
• Sync data from multiple devices through Strava

This makes it easy to bring your existing training history into Pace It and continue tracking your progress seamlessly.

Strava is a social feed and segment leaderboard. Pace It is an analytics layer that sits on top of any run source, including Strava itself.

Import your Strava runs and Pace It adds what Strava doesn't show: pace at each HR zone over months, training load, personalized target paces built from your last 60 days of running.

Strava shows your runs. Pace It shows whether your training is producing progress.

Android support is currently on the roadmap. We're actively working on bringing Pace It to Android devices. If you'd like early access, you can join the waitlist here.

In the meantime, Pace It is available on iOS and Apple Watch. If you have a Garmin, COROS or another device you can sync runs through the Strava integration.

Most running apps focus on tracking runs or giving training plans. Pace It focuses on helping you better understand your performance over time, making your pace and heart rate trends meaningful.

Instead of telling you what to do, it shows:

• How your pace changes at the same heart rate across weeks and months of training
• Whether your training is actually improving your fitness
• What your training paces (5k to ultra) should be based on your recent performance

This gives runners deeper insight into their progress and make targeted training decisions.

Overtraining happens when training volume or intensity ramps up faster than your body can recover. Pace It tracks your Training Load Ratio, which compares your recent load against your longer-term baseline.

A ratio between 0.8 and 1.3 means your training is productive:

• Below 0.8: you may be undertraining or tapering
• 0.8 to 1.3: productive training range
• 1.3 to 1.5: elevated load, monitor closely
• Above 1.5: injury-risk territory, consider reducing load

Pace It surfaces this so you can catch spikes before they become injuries.

Yes. Pace It includes a full Apple Watch app designed for serious runners. It supports 38 live metrics across 4 customizable screens, so you can configure exactly what you see during a run.

Key Apple Watch features:

• Structured interval workouts with warmup, work, recovery, and cooldown
• Pace and heart rate target feedback with haptic alerts
• 4 customizable metric screens with 38 live metrics
• Dashboard sync and watch complications

Built to surface the full metric set your Apple Watch already measures but the stock Workout app does not show.

Zone 2 is the aerobic base zone where your heart rate is at roughly 60 to 70 percent of maximum. Training here builds your aerobic engine and forms the foundation of distance running fitness.

Pace It tracks zone 2 training in two ways:

• Zone distribution chart: shows time in each HR zone over 12 weeks, so you can check your easy-to-hard ratio against the 80/20 target
• Pace by Heart Rate Zone trends: tracks your zone 2 pace month by month over 6 months, showing whether you are getting faster at the same effort

If your zone 2 pace is getting faster while heart rate stays the same, your aerobic fitness is improving.
